How much confidence do we have in the science?
Researchers use the scientific method to search for cause and effect relationships. This method requires that a
hypothesis be constructed. Scientists then design an appropriate well-controlled experiment to test that hypothesis. The results must be statistically significant and reproducible in order to be considered valid. There are a number of techniques that can be used to enhance the objectivity of a study as well as increase its statistical reliability.
In prospective medical research for example, we often use double blind, placebo controlled studies so that neither the researcher nor the patient knows if they are receiving the active drug or a placebo. This eliminates observer bias. Some times we cross the patient's over, so that the same patient takes both the active…

When the only tool you have is a hammer, the whole world looks like a nail. In other words, there is no problem that a bureaucrat can't solve, if only we would let them pass another regressive tax. That may well be the sum total of the creative thinking that has gone into the Obama
Cap-and-Trade plan. The Obama Administration proposes that companies buy a permit for each ton of carbon emitted, at an estimated cost, to start of $13 to $20 per ton. The permits could then be bought and sold. The theory behind this convoluted scheme is that it will somehow miraculously increase energy efficiency and renewable energy development.
Rather than focus on available technological solutions, let's burden hard working American consumers with another ill-conceived regressive tax! Who…

The key to producing less carbon dioxide emissions from fossil fuels is to use the fuel with the lowest carbon to hydrogen ratio. Coal is the least desirable because there are roughly 2 carbons for each hydrogen; oil is cleaner because it has the inverse ratio of approximately one carbon for 2 hydrogen molecules; and best of all is
methane (CH4), with 4 hydrogen molecules for each carbon molecule. Although
natural gas is primarily methane, it does contain, some longer chain hydrocarbons such as ethane, propane, butane, pentane etc. that make it slightly less desirable than pure methane. Thus, the reduction in
carbon dioxide emissions when natural gas is substituted for gasoline in an automobile is about 25-30%.
